Biography

David Ehrhardt has 25 years experience in the regulation and private finance of energy, water and other infrastructure, having advised on investments valued at over US$20 billion. Qualified in economics and law, he has authored numerous best practice guides to infrastructure regulation and public-private partnerships published by the World Bank and other international agencies, as well as academic articles. He has lectured on infrastructure economics and finance at Stanford and Georgetown Universities.

The combination of practical experience and theoretical rigor make him a convincing expert on quantum of damages. In the bilateral investment treaty case Biwater Gauff (Tanzania) Limited v United Republic of Tanzania* (ICSID Case No ARB/05/22) his evidence on quantum of damages convinced the panel to award no damages against the government, despite having found that government action amounted to expropriation. In a related case (City Water Services Ltd v Dar es Salaam Water and Sewerage Authority (UNCITRAL UN6761) his evidence led to an award of damages against for breach of contract in favour of the public party. In Mobil Exploration and Development Inc Suc Argentina and Mobil Argentina SA v Argentine Republic (ICSID Case No.ARB/04/16) David guided a team providing independent valuation advice to the panel on quantum of damages flowing from Argentina's actions to change energy regulatory and trading rules following the country's currency crisis.

David also testifies in regulatory cases and appeals. In Jamaica, his testimony in Jamaica Public Service Company Ltd v Office of Utilities Regulation (Appeal No 1 of 2013) persuaded the appeal panel to overturn the regulator's decision on a transmission wheeling tariff, holding that it was "irrational".
